9 Claims. (01.128-235) This invention relates to improvements in devices for applying dehorning paste to the horns of young cattle.

It is well known that thegrowth or development of horns can be arrested by applying .to

the horns of young cattle a paste containing certain chemicals which have this effect. Since such pastes are well known and readily obtainable on the .open market, their compositions will not be described in detail except to state that they frequently contain a powerful hydroxide that will cause blindness if it comes into contact with the animals eye and which may also injure other animals that may come in contact therewith.

Horns, even on young cattle, have a hardsurface layer that protects the interior and makes it necessary to apply the paste as close to the base of the horns as practicable.

It has been found that by scraping the horns adjacent their bases so as to destroy the protective action of the hard outer layer the paste will be more efiective and a less quantity may be used than where the horns are not scraped.

In U. S. Patent 2,420,582, granted May 13, 1947, a dehorning paste applicator is disclosed which is provided with means for scraping the horns near the base.

Where a cattle raiser has many cattle it is, of course, desirable to employ a tool or appplicator of such construction that its operation is rapid and which has means for replenishing the paste from a reservoir carried by the tool, and it is the object of this invention to provide such a tool.

It is a further object to produce a tool having an elastic applicator nozzle that can adapt itself to horns of various sizes and into which paste is fed from the reservoir.

It is another object to produce an applicator that can be operatedwithout the necessity of coming in close contact with the paste and which therefore removes the danger of injury from this source.

The above and any other objects that may become apparent as this description proceeds are obtained by means of a construction and an arrangement of parts that will now be described in detail and for this purpose reference will be had to the accompanying drawing in which the invention has been described and in which:

Figure 1 is a longitudinal diametrical section through the applicator,

Figure 2 is a view showing the manner of using the applicator,

Figure 3 is a fragmentary view, partly in section, showing the construction of the applicator nozzle, and

Figure 4 is a fragmentary section taken on line 4-4, Figure 3.

In the drawing, reference numeral 5 designates the incipient horn growth of a horn, which growth is to be arrested.

The applicator consists of an outer metal housing 6 that is cylindrical for the greater part of its length and has one end that tapers to a cylindrical section I that is threaded on its inner surface. The other end of the cylindrical member has a narrow zone 8 pressed outwardly to form a bayonet connection for holding a cover 9 in place. The cover 9 has anopening in which is secured a short tubular member having a head I. The opening in head I0 is threaded for cooperative engagement with the threaded plunger rod I l, the outer end of which has a hand wheel I2 by means of which it may be rotated.

A nozzle [3 has its inner and smaller end [4 threaded for cooperative engagement with the threads on the inner surface of section 1. The opening in the nozzle flares outwardly and is of a size suitable for receiving the incipient horn 5 shown dotted in Figure 1.

A glass reservoir I5 of a shape generally the same as the inside of housing 6 but of an outside diameter smaller than the inside diameter of housing 6 is positioned in the housing. Spacers l6 of rubber or some similar elastic material are provided to hold the reservoir in axial alignment with the housing. The reservoir tapers towards the nozzle and terminates in a cylindrical section I! of an outside diameter slightly larger than the normal inside diameter of the nozzle; the end of the reservoir serves to force the threads of the nozzle into the thread of the housing thereby holding the nozzle in place. The telescoping relation between the nozzle and the reservoir makes a tight seal that prevents paste from leaking into the housing.

The end of threaded rod II that terminates within the reservoir carries a piston, which in the present disclosure comprises two slightly spaced disks l8 held in place by nuts I 9. The piston and the manner in which it is attached to rod II has been illustrated in a general way only. It is to be understood that any suitable piston construction may be substituted for the one shown.

6. A tool for applying a growth inhibiting material to the horn of an animal, comprising; a reservoir containing the inhibiting material, a nozzle member secured to the reservoir, the nozzle 5 member being open at one end and adapted to telescope over the horn, scraping means projecting inwardly frqm the inside surface of the nozzle fr'ri'er-nber fadjacent the sopen e a the nozzle "memb'effor scraping theh'orr'r adjacent the base 10 thereof, means communicating the inside of the nozzle member with the reservoir, and means for -fee ding:the inhibiting material from the reservoir -'"and =through the last named means to deliver it have been shown as being interconnected P3 to the inside of the nozzle.
